Downdraft exhaust not working properly

Can you get to the switch terminals and try jumping them out with a piece of insulated wire? That would tell you if the switch is defective (my suspicion). Please be careful not to touch any live terminals - only the wire insulation you use for the jumper.

Hello friend, thank you for your post!

From my understanding you have some questions regarding the operation of your Frigidaire microwave. The fan will turn on when the temperature sensor recognizes the temperature is too hot. There should be suction from the bottom. If you are experiencing issues with your new microwave I would recommend contacting your manufacturer for proper warranty coverage. I hope this information is helpful to you. -Matt

Probably the switch or a burnt out resistor.

Generally there is a plug for the fan motor under the range, the panel where the drawer would be should lift off, you will then see the power to the fan motor. The fan motor is only 120Volts not 220V

always unplug electricity before attempting to repair on any electrical appliance

The downdraft is electric so there must be something malfunctioning with it. It is a high volume downdraft fan that is to be vented to the outside. Could it be that something has clogged the vent hole up, not allowing the fan to evacuate the smoke?

While I am not a big fan of Jenn-Air, their fans are usually high quality if they are installed correctly, with the proper vent lines.

Typically the Jenn-Air has a grill on the left hand side and the fan is suppose to come on when that burner is turned on.

you definalty should feels air moving, providing hte unit is ON. when not in use there should be mo draft( minimal at best) if there is still a draft when unit is off, i would check where it exhausts outside, there should be flap tha closes when not inuse

Hi
I have all the diagrams for that model and will gladly send them to you all for free via email. Remenber that the fan will always get gresse and have to be clean, also keep the filter clean.

Let me know were to send the diagrams...Glad to Help!!

Bearings are worn. You should be able to replace with a standard utility fan. You can find them at your local big box hardware store or order online here.
